Observer doesn't catch event Magento 2

Question

I have implemented 2 observers for checkout_cart_product_add_after, sales_order_place_after event. But these observers didn't catch events.

events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="sales_order_place_after">
        <observer name="websoftpro_utm_after_checkout_event" instance="WebSoftPro\UTM\Observer\SalesOrderAfterPlaceObserver" />
    </event>
    <event name="checkout_cart_add_product_complete">
        <observer name="websoftpro_utm_after_add_to_cart_event" instance="WebSoftPro\UTM\Observer\CheckoutCartProductAddAfterObserver" />
    </event>
</config>

Observer file

namespace WebSoftPro\UTM\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class CheckoutCartProductAddAfterObserver implements ObserverInterface
{

    /**
     * @param Observer $observer
     * @return void
     */
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $product = $observer->getEvent()->getProduct();
        $quoteItem =  $observer->getEvent()->getQuoteItem();
    }
}

I have used xdebug to debug. It went through this code:

$this->_eventManager->dispatch(
            'checkout_cart_product_add_after',
            ['quote_item' => $result, 'product' => $product]
        );

But it doesn't go to the Observer file.

What is the problem ?

Somebody, please help me out. Please!

I have found the solution in this post: Observer not working in Magento 2

For that to work:

1. Move the file events.xml to global (ModuleName/etc folder)
2. Clear all cache
3. run: php bin/magento setup:upgrade --keep-generated
